  46 # The following explanation may help to understand the use of the
  47 # version number fields: current, revision, and age.
  48 #
  49 # Consider that there are three possible kinds of reactions from
  50 # users of your library to changes in a shared library:
  51 #
  52 # 1. Programs using the previous version may use the new version as drop-in
  53 #    replacement, and programs using the new version can also work with the
  54 #    previous one. In other words, no recompiling nor relinking is needed.
  55 #    In short, there are no changes to any symbols, no symbols removed,
  56 #    and no symbols added. In this case, bump revision only, don't touch
  57 #    current nor age.
  58 #
  59 # 2. Programs using the previous version may use the new version as drop-in
  60 #    replacement, but programs using the new version may use APIs not
  61 #    present in the previous one. In other words, new symbols have been
  62 #    added and a program linking against the new version may fail with
  63 #    "unresolved symbols." If linking against the old version at runtime:
  64 #    set revision to 0, bump current and age.
  65 #
  66 # 3. Programs may need to be changed, recompiled, relinked in order to use
  67 #    the new version. This is the case when symbols have been modified or
  68 #    deleted. Bump current, set revision and age to 0.
